区域标志性形象:特征、构成与整合开发——以兰州市为例

区域标志性形象具有惟一性、象征性、传承性、资源性特征,其构成要素主要包括文化特色、景观塑造、空间布局、生态背景等。兰州自然环境意象独特,历史文化底蕴深厚,标志性形象的整合开发具有显著的区域优势,但目前存在的问题是,标志性形象的空间分布不均衡,景观形象不突出。鉴于兰州市标志性形象的现状,在综合分析区域差异和比较优势的基础上,提出该区域标志性形象的整合应构建兰州区域本底标志性形象,配置门户和窗口区域标志性,凸显黄河风情线整体标志性,塑造人与环境和谐的标志性。     

世界城市跨国空间研究的分野与合流

世界城市内部多种跨国要素作用形成的跨国空间已经成为一类新空间类型和客观存在。在跨国经济、跨国社会、跨国文化、跨国主义生活方式等跨国要素的交互作用下,跨国空间的形成发展、演绎逻辑表现出多样化分野。具体表现为：跨国空间在不同历史时期的分化、不同类型的差异以及全球化时代\"资本\"和\"生活\"的博弈,地方和空间的割裂与相互渗透等。在此基础上,对跨国空间的研究理念、形成机制和价值体系三方面却存在着合流的趋向,共同指向了全球化时代国家管治模式、自由主义生活方式以及软性制度的改革。     

Bone chemistry and the reconstruction of diet: Strontium discrimination in white-tailed deer

Studies of the relationship between the strontium content of human bone and past diet are still in an experimental stage. Because of the low frequency of carnivore remains at most archaeological sites and the absence of information on local strontium levels, it has been difficult to (1) estimate dietary intake for a prehistoric population, and (2) to compare prehistoric populations from spatially disparate areas. However, examination of strontium/calcium ratios in a modern herbivore may help to alleviate these problems. Bones from modern white-tailed deer (Odocoileus virginianus) were compared with deer diet in Wisconsin. An observed ratio between deer bone and diet in terms of a strontium/calcium index was calculated at 0204, which compares favourably with observed ratios reported for other mammals. Prehistoric white-tailed deer are used in the analysis of two Late Archaic sites in the midwestern U.S.A. The strontium levels in deer can be used as a baseline for comparison between sites. The prehistoric subsistence patterns are generally comparable, with hunting accounting for the bulk of the diet.     

Does it come from the Pays de Bray? Examination of an origin hypothesis for the ferrous reinforcements used in French medieval churches using major and trace element analyses

A new methodology based on major and trace element analyses of slag inclusions is proposed to determine (or exclude) the provenance of iron artefacts. It is applied to verify if the Pays de Bray, a French area between Rouen and Beauvais, could have been an important supplier for the ferrous reinforcements used in the Middle Ages for the building of churches and cathedrals in these two towns. To this purpose, the behaviour of trace elements during both direct and indirect operating chains is studied combining experimental smelting and different analytical methods, such as SEM–EDS, ICP–MS, LA–ICP–MS and INAA, performed on archaeological samples. The chemical signature of the Pays de Bray iron ore and slag is determined considering MnO and P₂O₅ contents as a first rough filter and seven couples of trace elements. Then, the major and trace elements are analysed using the same methods in the slag inclusions of 32 artefacts from the Beauvais and Rouen churches, made by the bloomery process. The trace element signature of the inclusions from each artefact is compared with the ore from the Pays de Bray area. The iron used in the Rouen and Beauvais churches seems not to come mainly from the Pays de Bray.     

The shell game: analytic problems in archaeological mollusc quantification

MNI calculations for archaeological molluscs that rely on counts of non-repetitive elements (NREs) are popular for their analytic speed and efficiency. Yet the reliability of this approach as compared to ‘traditionally’ calculated MNI has not been explored. Here, I examine these approaches using data from the Caribbean coastal midden site of Grand Bay, Carriacou. Results suggest that an NRE-based approach to MNI calculation can be unreliable under certain circumstances. In addition, dependence on the NRE-based method may hinder the integration of invertebrate with vertebrate data, obscuring a holistic understanding of prehistoric diet and resource exploitation. These findings are discussed in relation to practical constraints and fulfillment of zooarchaeological goals.
